Question

Guys please solve this as fast as possible

Answer 1

Answer:

1:Frequency

2:about 20 Hz to 20 kHz

3:A Vacuum

4:Period .T

5:Noise

2...1:n physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.

Explanation:

Answer 2

1. Hertz

2. about 20 Hz to 20 kHz

3. Vacuum

4.  the period T

5.  noise

1. In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid, or solid.

2.  Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

3. No, all the bodies cannot produce sound.

4. When we touch a sound-producing bell, we can feel the vibration.

5. amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position

6. The larynx is also called a voice box which is the sound-producing organ of human beings.

7. Vocal cords are the thin bands of muscle in the back of your throat that move to produce the voice.

8. Hertz is a unit for measuring the frequency of sound waves.

9. The frequency range of audible sound is 20 Hz to 20 kHz.
